SANCTIONS FOR BREACH OF OBLIGATION
If the debtor does not perform his obligation , it is theoretically possible to force him to do so (compulsory performance).
The specific performance is not always possible or permitted and the creditor will then settle for damages ( with equivalent performance ).
In synallagmatic contracts , if one party does not perform his obligation, the other may suspend the performance of his (exception of non-performance) and even request the resolution or termination of the contract for non-performance (article 1184 of the Civil Code ).
In addition, the non-performance of a contractual obligation is a civil fault which engages the contractual liability of its author, therefore exposes him to compensation through a judgment for damages.
